Man, I need to dust off my pedal board. This is it. My last pedal. The flanger is simultaneously my favorite and least useful effect. This was a pedal I acquired about 15 years ago when I was doodling on guitar. I had the space left on the pedalboard to try it out. So I did. I don't play any Tool, which is what immediately springs to my mind when I think of flanger on bass, so I guess I'll have to write a song just to have an excuse to really use this bad boy.
This is not the older BF-2B that was made for bass, nor the current Boss flanger BF-3 that has a separate input for bass. Sometimes there is a "tone-suck" issue when using bass through "guitar" pedals, but I don't feel that is the case with the BF-2. It has a really great sound. I would like to share a sample, and since I'm feeling pretty lazy today, I'm just going to link you a video someone else made instead of doing one myself:
It has four controls: Manual controls the delay of the flange (not sure why they didn't just call it delay), Depth controls the range of the flange, Rate controls the speed of the oscillation and Res is like a gain control for the flanging effect. The controls are very responsive, allowing you to generate a whole range of sounds. Like all Boss pedals it is built like a brick. If you are thinking about picking one up, check out the manual here. I checked eBay, and it looks like these are now considered a "vintage" and therefore highly sought after pedal. The prices ranged from $80-$150, but I imagine if you could buy one from an actual person as opposed to an eBay store, the cost would be somewhat less.
So that's it. The only piece of gear I have left is my huge Kustom combo amp. I guess I'll have to hurry up and get another pedal to play with...
